Abstract
Insect sterility technology is gradually being applied to the control of lepidoptera pests, and the target gene for male sterility is the core of this technology. JMS is a mutant silkworm that exhibits male sterility, and to elucidate its formation mechanism, this study conducted a full transcriptome analysis of the testes of JMS and its wild-type silkworms 48 h after pupation, identifying 205 DElncRNAs, 913 mRNAs, and 92 DEmiRNAs. The KEGG pathway enrichment analysis of the DEmRNAs revealed that they were involved in the biosynthesis of amino acids and ECM-receptor interactions. Combined with ceRNA regulatory network KEGG analysis suggests that pathways from amino acid biosynthesis to hydrolytic processes of protein synthesis may play a crucial role in the formation of JMS mutant variants. Our study deepens our understanding of the regulatory network of male sterility genes in silkworms; it also provides a new perspective for insect sterility technology.

Abstract
The spatiotemporal expression patterns of genes are crucial for maintaining normal physiological functions in animals. Conditional gene knockout using the cyclization recombination enzyme (Cre)/locus of crossover of P1 (Cre/LoxP) strategy has been extensively employed for functional assays at specific tissue or developmental stages. This approach aids in uncovering the associations between phenotypes and gene regulation while minimizing interference among distinct tissues. Various Cre-engineered mouse models have been utilized in the male reproductive system, including Dppa3-MERCre for primordial germ cells, Ddx4-Cre and Stra8-Cre for spermatogonia, Prm1-Cre and Acrv1-iCre for haploid spermatids, Cyp17a1-iCre for the Leydig cell, Sox9-Cre for the Sertoli cell, and Lcn5/8/9-Cre for differentiated segments of the epididymis. Notably, the specificity and functioning stage of Cre recombinases vary, and the efficiency of recombination driven by Cre depends on endogenous promoters with different sequences as well as the constructed Cre vectors, even when controlled by an identical promoter. Cre mouse models generated via traditional recombination or CRISPR/Cas9 also exhibit distinct knockout properties. This review focuses on Cre-engineered mouse models applied to the male reproductive system, including Cre-targeting strategies, mouse model screening, and practical challenges encountered, particularly with novel mouse strains over the past decade. It aims to provide valuable references for studies conducted on the male reproductive system.

Abstract
The cryopreservation-thawing process of spermatozoa cells has negative impacts on their structure, function, and fertility parameters, which are known as cryoinjury. Asthenozoospermia patients are more susceptible to cryoinjury. Granulocyte-macrophage colony-stimulating factor (GM-CSF) increases sperm glucose uptake via the induction of glucose transporters, resulting in increased sperm motility. This study aimed to investigate the efficiency of GM-CSF supplementation of the cryopreservation media for semen samples of asthenoteratozoospermia patients. The study was carried out on 20 semen samples from infertile men referred to diagnosing semen analysis. To avoid subjective bias, two main sperm motility parameters, including velocity along the curvilinear path and velocity along the straight-line path were considered by the computer-assisted sperm analysis system. Afterward, each semen sample was divided into three equal aliquots and randomly assigned to one of the following groups: group I (control, freezing media only), group II (+GM-CSF, freezing medium supplemented with 2 μL/mL GM-CSF), or group III (GM-CSF added after thawing and washing). Following semen thawing, standard parameters, mitochondrial membrane potential (MMP), and the DNA Fragmentation Index were analyzed. Total sperm motility (progressive and non-progressive) improved significantly in group III samples after a 30-minute incubation with GM-CSF compared with the control group (26.5% ± 3.1% vs. 17.51% ± 2.59%). However, no differences in progressive motility or sperm morphology were found among the three thawed samples. The percentage of vitality was significantly higher in group III compared with the other two groups (28.38% ± 3.4% vs. 22.4% ± 3.08% and 22.14% ± 2.77%, respectively) (p < 0.05). JC-1 levels (a marker of MMP) were not significantly different between the examined groups (44.95% ± 8.26% vs. 36.61% ± 6.95% vs. 46.67% ± 7.7%, for control, group II, and group III, respectively) (p > 0.05). GM-CSF may be advantageous as an additive after freezing, improving total motility and viability after 30 minutes of post-thaw incubation; however, when supplied to the freezing media before cryopreservation, it is unable to protect against cryoinjury.

Protein posttranslational modifications in health and diseases: Functions, regulatory mechanisms, and therapeutic implications. MedComm (Beijing) 2023; 4:e261.

Abstract
Protein posttranslational modifications (PTMs) refer to the breaking or generation of covalent bonds on the backbones or amino acid side chains of proteins and expand the diversity of proteins, which provides the basis for the emergence of organismal complexity. To date, more than 650 types of protein modifications, such as the most well-known phosphorylation, ubiquitination, glycosylation, methylation, SUMOylation, short-chain and long-chain acylation modifications, redox modifications, and irreversible modifications, have been described, and the inventory is still increasing. By changing the protein conformation, localization, activity, stability, charges, and interactions with other biomolecules, PTMs ultimately alter the phenotypes and biological processes of cells. The homeostasis of protein modifications is important to human health. Abnormal PTMs may cause changes in protein properties and loss of protein functions, which are closely related to the occurrence and development of various diseases. In this review, we systematically introduce the characteristics, regulatory mechanisms, and functions of various PTMs in health and diseases. In addition, the therapeutic prospects in various diseases by targeting PTMs and associated regulatory enzymes are also summarized. This work will deepen the understanding of protein modifications in health and diseases and promote the discovery of diagnostic and prognostic markers and drug targets for diseases.

Abstract
As an autoimmune disorder, vitiligo is characterized by depigmented skin macules. CD8+T cells and macrophages enrichment promote the onset of vitiligo, while the role of macrophages to CD8+T is not well deciphered. To develop a mouse model of vitiligo with prominent epidermal depigmentation, Krt14-Kitl* transgenic mice containing an elevated number of melanocytes in the epidermis with membrane-bound Kit ligand (Kitl*) were adoptively transferred with premelanosome protein (PMEL) CD8+ T cells. On the other hand, Krt14-Kitl* mice were mated with ubiquitin-specific protease 34 (USP34)MKO mice to decipher the role of USP34 in vitiligo. Vitiligo scores and PMEL CD8+ T cell enrichment were detected with flow cytometry. Human peripheral blood mononuclear cells (PBMCs) or mice bone marrow-derived macrophages (BMDMs) were incubated with lipopolysaccharide (LPS), CpG, or co-incubated with KU-55933, an ataxia telangiectasia-mutated (ATM) inhibitor. Chemokine (C-C motif) ligand 2 (CCL2), Ccl5, and interleukin (Il)-12α expression was assayed with real-time PCR, and p-IKKα/β was assayed with Western blots. USP34 was up-regulated in the PBMCs of vitiligo patients and LPS-stimulated BMDMs. USP34 deficiency did not affect the differentiation of CD11b+F4/80+ macrophages in the bone marrow. Immunoprecipitation demonstrated the interaction between USP34 and ATM. USP34 deficiency or KU-55933 administration promoted the induction of Ccl2, Ccl5, Il12α, and p-IKKα/β in LPS or CpG stimulated BMDMs; KU-55933 administration could not affect the expression of the above molecules in USP34 deficient BMDMs. It further revealed that USP34 deficiency promoted the development of vitiligo with increased PMEL CD8+ T cell enrichment, which was not affected by KU-55933 administration. USP34 deficiency in macrophages promotes the onset of vitiligo with increased PMEL CD8+ T cell enrichment, and USP34/ATM complex can be considered as a therapy target.

Abstract
Ubiquitination and deubiquitination are reversible processes that modify the characteristics of target proteins, including stability, intracellular localization, and enzymatic activity. Ubiquitin-specific proteases (USPs) constitute the largest deubiquitinating enzyme family. To date, accumulating evidence indicates that several USPs positively and negatively affect metabolic diseases. USP22 in pancreatic β-cells, USP2 in adipose tissue macrophages, USP9X, 20, and 33 in myocytes, USP4, 7, 10, and 18 in hepatocytes, and USP2 in hypothalamus improve hyperglycemia, whereas USP19 in adipocytes, USP21 in myocytes, and USP2, 14, and 20 in hepatocytes promote hyperglycemia. In contrast, USP1, 5, 9X, 14, 15, 22, 36, and 48 modulate the progression of diabetic nephropathy, neuropathy, and/or retinopathy. USP4, 10, and 18 in hepatocytes ameliorates non-alcoholic fatty liver disease (NAFLD), while hepatic USP2, 11, 14, 19, and 20 exacerbate it. The roles of USP7 and 22 in hepatic disorders are controversial. USP9X, 14, 17, and 20 in vascular cells are postulated to be determinants of atherosclerosis. Moreover, mutations in the Usp8 and Usp48 loci in pituitary tumors cause Cushing syndrome. This review summarizes the current knowledge about the modulatory roles of USPs in energy metabolic disorders.

Abstract
Protein ubiquitination with general existence in virtually all eukaryotic cells serves as a significant post-translational modification of cellular proteins, which leads to the degradation of proteins via the ubiquitin–proteasome system. Deubiquitinating enzymes (DUBs) can reverse the ubiquitination effect by removing the ubiquitin chain from the target protein. Together, these two processes participate in regulating protein stability, function, and localization, thus modulating cell cycle, DNA repair, autophagy, and transcription regulation. Accumulating evidence indicates that the ubiquitination/deubiquitination system regulates reproductive processes, including the cell cycle, oocyte maturation, oocyte-sperm binding, and early embryonic development, primarily by regulating protein stability. This review summarizes the extensive research concerning the role of ubiquitin and DUBs in gametogenesis and early embryonic development, which helps us to understand human pregnancy further.

Abstract
Non-obstructive azoospermia (NOA) is one of the most important causes of male infertility. Although many congenital factors have been identified, the aetiology in the majority of idiopathic NOA (iNOA) cases remains unknown. Herein, using single-cell RNA-Seq data sets (GSE149512) from the Gene Expression Omnibus (GEO) database, we constructed transcriptional regulatory networks (TRNs) to explain the mutual regulatory relationship and the causal relationship between transcription factors (TFs). We defined 10 testicular cell types by their marker genes and found that the proportion of Leydig cells (LCs) and macrophages (tMΦ) was significantly increased in iNOA testis. We identified specific TFs including LHX9, KLF8, KLF4, ARID5B and RXRG in iNOA LCs. In addition, we found specific TFs in iNOA tMΦ such as POU2F2, SPIB IRF5, CEBPA, ELK4 and KLF6. All these identified TFs are strongly engaged in cellular fate, function and homeostasis of the microenvironment. Changes in the activity of the above-mentioned TFs might affect the function of LCs and tMΦ and ultimately cause spermatogenesis failure. This study illustrate that these TFs play important regulatory roles in the occurrence and development of NOA.

Abstract
The Cre-loxP system is widely used to investigate the cell-type specific
roles of genes of interest. Cre-driver mice are required for cell-type
specific knockout during the Cre-loxP reaction. To maintain
Cre-driver mouse strains, Polymerase chain reaction (PCR)-oriented
genotyping targeting the Cre gene cassette is usually conducted. In this
study, we instead applied a colorimetric loop-mediated isothermal amplification (LAMP)
method for Cre-genotyping. Among four sets of primers designed by the
in silico program, one set effectively amplified the
Cre cassette of three Cre-driver strains, but not of
C57BL/6 mice. This LAMP-oriented method reduces assay time by less than half compared to
the PCR-based method, and can be carried out using a conventional isothermal incubator.
Applying this LAMP method may accelerate genotyping of Cre-driver
mice.

Abstract
Ubiquitin specific protease (USP) 2 is a multifunctional deubiquitinating enzyme. USP2 modulates cell cycle progression, and therefore carcinogenesis, via the deubiquitination of cyclins and Aurora-A. Other tumorigenic molecules, including epidermal growth factor and fatty acid synthase, are also targets for USP2. USP2 additionally prevents p53 signaling. On the other hand, USP2 functions as a key component of the CLOCK/BMAL1 complex and participates in rhythmic gene expression in the suprachiasmatic nucleus and liver. USP2 variants influence energy metabolism by controlling hepatic gluconeogenesis, hepatic cholesterol uptake, adipose tissue inflammation, and subsequent systemic insulin sensitivity. USP2 also has the potential to promote surface expression of ion channels in renal and intestinal epithelial cells. In addition to modifying the production of cytokines in immune cells, USP2 also modulates the signaling molecules that are involved in cytokine signaling in the target cells. Usp2 knockout mice exhibit changes in locomotion and male fertility, which suggest roles for USP2 in the central nervous system and male genital tract, respectively. In this review, we summarize the cellular events with USP2 contributions and list the signaling molecules that are upstream or downstream of USP2. Additionally, we describe phenotypic differences found in the in vitro and in vivo experimental models.
